SPRING AIR-GUN.

SPECIFICATION forming part of Letters Patent No. 439,246, dated Octoberl28, 1890. Application led March 24, 1890. `Serial No. 345,041. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES M. JosLIN, a citizen of the United States, residing at Northville, county of W'ayne, State of Michigan, have invented a certain new and useful Improvement in Air-Guns and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to new and useful improvements in air-guns; and it consists of the devices and appliances, with their combinations and arrangements, as herein specified and'claimed, and more fully illustrated in the accompanying drawings, in which- Figurel is aside elevation. Fig. 2 is a longitudinal vertical section. Fig. 8 is a plan view with the cap removed. Fig. 4 is a vertical cross-section on the line a; Fig. 2. Fig. 5 is a similar section on the line y y, Fig. 2; and Fig. 6 is a similar view on the line as, Fig. 2. i

The object of my invention is to provide a air-gun of simple, durable, and el`n`cient construction, and which shall be capable of bein g manufactured so economically as to be retailed at a very low figure. To these ends I carry out my invention as follows:

A represents the stock, provided with breech A and barrel A2, made of wood, the barrel having a removable cover or cap A3.

B denotes a Ametal air-chamber provided with a metal barrel B communicating therewith.

C denotes the plunger, constructed with the usual reciprocatory head C and stem C2.

D is the spring to retract the plunger to compress the air in the air-chamber.

E is a locking-arm engaged upon the stem of the plunger, and F a returnrod sleeved through said arm. This rod may simply be bent at its forward end, as shown at f, to prevent its disengagement with the lockingarm. So, also, the rear end is bent, as shown at f', to engage the operating-lever. G denotes said lever, which I prefer to construct with a laterally-extended arm G', provided with a perforated shoulder G2 to engage the returnrod. The rear of the lever is also downwardly extended, as shown at G3, through which the lever is fulcrumed upon the stock A, preferably by a bolt G4, provided with a nut thereupon to hold the lever rmly in place and in a durable manner, effectually withstanding all strain thereon. The portion G3 of said lever may extend downward alongthe outside of the stock, as shown in Fig. l, or it may extend downward through or into a recess in the stock in the rear of the barrel, as shown in Fig. 2. The lever is so constructed andarranged as to lie down along the side of the barrel when in normal position, as shown.

H is the trigger, the detent h whereof engages the lower end of the locking-arm E when the spring has been compressed.

To locate the air-chamber B, with its barrel B and spring-actuated plunger C, in place in the Wooden stock, the wooden barrel is recessed intermediate its ends, as shown at a, to receive the air-chamber, and along the forward end, as shown at a', to receive the metal barrel, and also along the rear end, as shown at a2, to receive the spring-actuated plunger, return rod, and connected parts adjacent thereto. Vhen the said chamber and metal barrel are in place, I prefer to close the recess aff above the metal barrel with a strip a3. Over all the cap A3 is then engaged, as by screws A4, holding the air-chamber and related parts in place and closing the stock, although the cap is not essential, as the gun would Work efficiently Without it. It will be observed that by so recessing thewooden barrel to receive the air-chamber the woodcnbarrel abuts firmly against both ends of the aire. chamber, as shown at a4 and a5, holding the IOC barrel and breech, of an air-chamber provided `with a spring-actuated plunger, a looking-arm engaged upon the stem of the plunger, a return-rod for retracting said arin, and an operating-lever constructed with a laterally-projecting arm to connect with the plunger.

3. In an air-gun, the combination, with a Wooden barrel and breech, of a separable aircharnber provided -with a springactuated plunger, a locking-arn1 engaged upon the stem of the plunger, and a return-rod sleeved through said arm, substantially as set forth.

4.V In an air-gun, the combination, with the spring-'actuated plungergof an operating-leverfulcrurned to the stock of the gun,v said lever constructed with a laterally-extended arm to connect with the plunger, the forward end of said lever in its normal position lying adjacent to the side of the stock of the gun, substantially as set forth;

5. In an air-gun, the combination, with a spring-actuated plunger provided with a locking-arm and a return-rod engaged therewith, of an operating-lever constructed with a laterally-extended arm connected with said rod, said lever fulcrurned at its rear end to the stock of the gun, its forward end in its normal position lying at the side of the stock, substantially as set forth.

ln testimony whereof l sign this specification in the presence of two witnesses.
